Arizona running back Ka’Deem Carey is facing domestic violence charges that are expected to be filed against him later this week, according to multiple reports.

Carey, a sophomore who led the nation in rushing this season, was investigated by the Tucson, Ariz. police from an incident in December. He allegedly had an altercation with his pregnant ex-girlfriend on Dec. 23.

According to Tucson police, he reportedly tried to enter her house “to get a lighter to smoke drugs.” When she didn’t let him in, he allegedly pushed her down and then slammed the door on her hand.

Carey tried to get a restraining order against the 23-year-old woman and her mother, but the request was denied.

“I’ve spoken with Ka’Deem and am aware of the case,” Arizona coach Rich Rodriguez said. “We take these matters very seriously and will support the authorities however we can. Once more specific information is available, we will act accordingly.”
